Default radiators hold power huh?

so im doing some testing, and the potential difference from pos to neg on my battery terminals is 12.7, normal. I go and put the ground on the radiator just for shits and giggles, lo and behold i get a potential difference of 12.9

did one of these



what the hell phenomenon is this?

im reading up on electrolysis in cooling systems and starting to wonder if this is a serious thing i should be concerned with

just did an actual test, getting about 200mv/.2v of potential from the negative post of the battery to the coolant. not quite at the .3v threshold of electrolysis but concerning nonetheless. i didnt do the run with the vehicle on so we'll see if that makes a difference

leads me to my next question, should be perfectly fine to run the engine with the coolant cap off right? obviously not to drive it, just to let the thermostat open up, have the coolant being circulation, and to check the potential

i need the thermostat open though.. i dont plan on doing it longer than a minute or two because ill need to turn on and off things to diagnose where its coming from (if i find its coming at all)

do you like your engine being eaten alive from the inside out? I think it's a very important thing that I've NEVER heard of. I hope my mechanic checks these things when he installed my last radiator.

electrolysis causes pitting in aluminum and can cause a radiator to fail in as little as a month. some engine blocks made of aluminum are especially susceptible

Quote:
Field Problems That Led To This Test Procedure
1. Copper injector shells in a truck engine were being destroyed in 3D days because a broken cab ground strap allowed the electrical current to ground through the coolant.

2. A twelve cylinder marine engine was destroyed by liner pitting. As indicated by our laboratory testing of the coolant, the overhauled engine was again damaged. The starter, which was starting the engine with no apparent problem to the operator, was causing a 12 volt current to ground through the coolant.

Pitting destroyed engine blocks in a large towboat. The pitting was, caused by an electrical current due to two defective electrical switches on the after cooler systems and one switch on the air conditioning unit in the captain's cabin.

4. The aluminum top tanks of truck radiators were pitting on a new fleet of trucks equipped with rubber air bag suspension an the rear ends. The rear ends were generating a current, which passed up the drive shaft to the cooling system. Grounding the rear ends and transmissions stopped the problem before the engines were destroyed.

5. A large fleet of trucks made up of half tankers and half flatbeds, using the same brand of engines and trucks, lost sixty engines in one year. Fifty-four engines failed in the flatbeds while only six engines failed in the tankers. Tankers have a bonded ground system while flatbeds do not. The nine to one ratio indicates the potential for damage.

6. A truck hauling plastic pipe was losing the engine every 100,000 miles. The operator noted the load was glowing because of static electricity due to air brushing down the open-ended pipes. The operator covered the pipe with a tarp and the engine lasted over 300,000 miles,

7. Newer model electronic controlled engines, head gaskets, water pumps, radiators, oil cooler, and transmissions were being damaged. Capacitors in the computers were allowing a stored electrical current to enter the coolant when the engines where turned off or starting after a period when the engine was in not in use. The electrical current has been present even with the batteries removed from the unit.

8. Grounding systems with the computer grounded direct to the batteries are beginning to be used by several manufacturers. Contact your manufacturer service-engineering department if a current is noted.

Ground your apt to battery negative. Problem solved

One thing I do for machines with bad electrolysis is put a stainless or titanium tube right before the aluminum or copper that would be eaten
The stainless usually lasts 10-20 years and titanium a solid 20 years

But it is always better to fix the problem

unfortunately thats not an option, maybe on industrial equipment. i'm still working on figuring it out but i have a sneaking suspicion that my headlights and dash circuit are guilty, but they're grounded in my bcm.

i need some insight from someone who actually understands the electrical system in 99-06 GM trucks and can tell me where the common problem is (likely a computer ground or something)

the problem is funky, it almost seems like when the alternators or engine is turned on the problem dissipated - but my meter is hardly high quality accuracy and the probe is far from ideal for a liquid. a copper tube would be better but im not bothering.

ended up with about .06-.07 or 60-70 millivolts after testing it for a more realistic reading. that would be perfectly fine, however the initial reading irked me so im going to test it when its fully hot again in a few days. i may also get a ph test and determine what the coolant is sitting at, as that'll be a good indication if electrolysis is occurring.

oh and regarding grounding the alternators, already did that, initially found my 2nd batt ground was far from ideal so i replaced it by adding a ground to the oem firewall "bussbar" and it made a difference in audible loudness so i know the 2nd battery is actually pumping now. in any case, simply grounding alt to batt wont fix a problematic grounding situation where someone grounds a component to the radiator or its bracket, or grounds the radiator incorrectly. i need to trace some more wires.

Ground the rad to the battery. That should dissipate any charge that builds up instantly. Doesn't need to be a big wire.

In reality though I don't think there's anything wrong.
